/*
 * The back office, in Tourkeep's own design language.
 *
 * Same tokens as `app/globals.css`, so the two surfaces cannot drift apart on
 * colour or type. What differs is density: this is an operational tool read in
 * columns, so rows are tighter, the type scale is smaller, and cards are used
 * only where something genuinely is a separate object.
 *
 * Light is derived the same way the app derives it: grounds invert, status
 * colours darken enough to read on white, and text on a coloured fill uses
 * --on-text.
